A major complaint about Google's Chrome web browser has been that so far, it is still not available on anything other than Windows. Google promised to deliver Chrome to Mac OS X and Linux as well, but as it turns out, this is a little harder than they anticipated, Ben Goodger, Google's Chrome interface lead, has explained in an email. It has also been revealed what toolkit the Linux version of Chrome will use: Gtk+.

"...Chrome was meant for windows and then after the fact they decided to go x-platform.

Citation not needed as this was an opinion.
Gnome having more users and KDE was referencing an objective fact. I would also add that clearly Chrome was meant for Windows first. I mean its obvious they only began porting to other platforms after Chrome was released for Windows. I am sure they knew they would have to create versions for other platforms but it hardly seemed a priority for them, at least initially. Emphasis on 'seemed'.
